I used the calipers off a Challenger - same issue. There's some pad overhang, but it's a nut and bolt swap for Gen 2 trucks (built from 86 up) hub and spindle assemblies. You will need to cut a small notch out of the stock backing plate as it fouls the twin piston caliper. 5 minute job with an angle grinder. I opted for braided teflon sleeved lines as well.
